Description

Abfederung für Kraftfahrzeuge Die Erfindung bezieht sich auf eine Abfederung für Kraftfahrzeuge, deren Räder durch aus Lenkern gebildete Parallelogramme oder Vierecke gegenüber dem Rahmen geführt sind.Suspension for motor vehicles The invention relates to a Cushioning for motor vehicles, the wheels of which are made up of parallelograms formed from handlebars or squares are guided opposite the frame.

Bei der Abfederung nach dem Patent 593 897 greifen an den Drehzapfen der Lenker Drehfedern ,an, die im wesentlichen gleich große Momente für die Lenkerergeben. Die Drehzapfen der Lenker sind in- diesem Falle durch Bunde und Scheiben im Lagergehäuse axial geführt, so, daß in horiziontaler Richtung keine Federung möglich ist. Eine solche H!orizo:ntalfederung ist jedoch erwünscht, um die beim Durchfahren ,einer Kurve oder beim Anfahren an einen Randstein auftretenden erheblichen Querkräfte elastisch nachgiebig auf den Rahmen zu übertragen und dabei die Lenker nicht nur unter den Vertikalkräften, sondern auch unter den Horizontalkräften im wesentlichen gleichartig zu beanspruchen.In the spring suspension according to patent 593 897, grip on the pivot pin the handlebar torsion springs, which give substantially equal moments for the handlebars. The pivot pins of the handlebars are in this case in the bearing housing by means of collars and washers axially guided so that no suspension is possible in the horizontal direction. One Such H! orizo: ntalfederung is desirable, however, in order to avoid the when driving through, one Curve or when approaching a curb significant lateral forces occurring to transfer elastically yielding to the frame and not only the handlebars under the vertical forces, but also essentially under the horizontal forces to claim similarly.

Das Neue der Erfindung besteht darin, daß die Tragzapfen der Lenker auch in axialer Richtung abgefedert sind. Dadurch können die auf das Rad gelangenden, in diese Richtung fallenden Seitenstöße ebenfalls gleichmäßig von beiden Lenkern aufgenommen werden, so, daß eine einseitige zusätzliche Beanspruchung der Lenker nahezu ohne Änderung der Parallelführung der Räder vermieden ist. Die Lenker bleiben somit sowohl unter, den Vertikalkräften als auch unter den Horizontalkräften im wesentlichen gleich beansprucht, wodurch bei gleicher Ausführung auch gleiche Haltbarkeit erzielt wird.The novelty of the invention is that the trunnions of the handlebars are also cushioned in the axial direction. This allows those who get on the bike Side impacts falling in this direction are also applied equally from both links be added, so that a one-sided additional stress on the handlebars is avoided almost without changing the parallelism of the wheels. The handlebars remain thus both under the vertical forces and under the horizontal forces in the essentially equally stressed, which means that the same design also has the same durability is achieved.

Der Gegenstand der Erfindung ist auf der Zeichnung in einem Ausführungsbeispiel, und zwar in Anwendung auf in Fahrtrichtung schwingende gelenkte Räder näher veranschaulicht. Es zeigt: Fig. i einen etwa senkrechten, quer zur Fahrtrichtung verlaufenden Schnitt durch die Radaufhängung, Fig.2 eine zugehörige Draufsicht und Fig.3 ein Schaubild des seitlichen Kraftangriffs.The object of the invention is shown on the drawing in an exemplary embodiment, specifically illustrated in more detail in application to steered wheels swinging in the direction of travel. It shows: FIG. 1 an approximately vertical section running transversely to the direction of travel through the wheel suspension, FIG. 2 a corresponding plan view and FIG. 3 a diagram of the lateral force application.

Das Rad 2 wird durch die Kugelgelenke getragen, die neben der Schwingbewegurlg auch die Lenkbewegung desselben ermöglichen. Die mit den Lenkerenden 14, 15 verbundenen Kugelzapfen 8, 9 ruhen in Pfannen i o, i i des Achsschenkelträgers. Die Drehzapfen 23, 24 der Lenker i 6, 17 lagern in den Enden der parallel üb:ereinanderliegenden Querrohre 58, 58a außen in Nadellagern 25, 26 und innen in Gle.itb chsen 25a, 26a. Die Drehzapfen 23, 24 sind mit gleichachsigen Federstäben 41, 42 verbunden, die an den radseitigen Enden durch Vierkante 3 i, 32 gegen Drehung und durch Stifte 39, 39a gegen Längsverschiebung gesichert sind. Die Federstäbe 41, 42 erstrekken sich durch ihre Widerlager 45, 46 -in den Querrohren 58, 58a hindurch und sind in der Längsmittelehene des Wagens durch Vierkante 43, 44. gegen Drehung und durch Körnerschrauben 53,54 gegen Längsverscbiebungge;. sichert. Die Drehzapfen 23, 24 sind durch die. Federstäbe 41, 42 in axialer Richtung gehalten. In die rahrnenseitigen Enden der Drehzapfen 23, 24 greifen Schraubenbolzen 39, 4o mit so viel Spiel ein, daß die notwendige axiale Bewegung der Drehzapfen nicht behindert wird. Die Enden der Querrohre 58, 58a sind durch Gummiringe 6o, 6r abgedichtet. Die Querrohre sind durch Stege 62 zu ,einem Querträger vereinigt, der .an den Längsmittelträger 63 angeflanscht ist.The wheel 2 is carried by the ball joints which, in addition to the swing movement, also enable the steering movement of the same. The ball pivot connected to the arm ends 14, 1 5 8, 9 resting in pans io, ii of the steering knuckle. The pivot pins 23, 24 of the links i 6, 17 are supported in the ends of the parallel cross tubes 58, 58a on the outside in needle bearings 25, 26 and on the inside in sliding sleeves 25a, 26a. The pivot pins 23, 24 are connected to coaxial spring bars 41, 42 which are secured against rotation at the ends on the wheel side by square edges 3 i, 32 and against longitudinal displacement by pins 39, 39a. The spring bars 41, 42 extend through their abutments 45, 46 -in the cross tubes 58, 58a and are in the longitudinal center plane of the carriage by square edges 43, 44. against rotation and by center screws 53, 54 against longitudinal displacement ;. secures. The pivot pins 23, 24 are through the. Spring bars 41, 42 held in the axial direction. In the ends of the pivot pins 23, 24 on the side of the frame, screw bolts 39, 40 engage with enough play that the necessary axial movement of the pivot pins is not hindered. The ends of the cross tubes 58, 58a are sealed by rubber rings 6o, 6r. The cross tubes are united by webs 62 to form a cross beam which is flanged to the longitudinal center beam 63.

Schwingt das Rad 2 durch, so üben die Federstäbe 41, 42 im wesentlichem gleiche Momente auf die Lenker 16, 17 aus. Die Schwenkung des Rades 2 erfolgt um die Verbindungslinie der Kuge1zaapfen 8, 9 als Lenkachse. Greift ,an dem Rad 2 eine Querkraft Q an, wie Fig.3 zeigt, so entsteht ein Kippmnoment Q # r, wenn r den wirksamen I,',adbalbmesser bedeutet. Dieses Kippmoment wirkt auf die Lenker 16, 17 in Form eines Kräftepaares S # h, wenn !a den senkrechten Abstand der Drehzapfen 23, 24 bedeutet. An dem oberen Drehzapfen 24 greift siomit eine Zugkraft S und an dem unteren Tragzapfen 23 eine Druckkraft S an. Da die Drehzapfen 23, 24 nur durch die Federstäbe 44 42 axial gehalten werden, so -werden die Kräfte S unmittelbar von diesen aufgenommen; der obere Federstab 42 wird hierbei auf Zug und der untere Federstab 4 1 ,auf Druck beansprucht. Da die Elastizität der Federstäbe 44 42 unter Axialkräften naturgemäß zu gering ist, um die erwünschte Federung sicherzustellen, werden die Federstäbe 4r, 42 leicht vorgekrümmt, so daß an die Stelle der Zug- und Druckbelastungen Biegungs- und Knickbelastungen treten. Die _Drehzapfen 23, 24 werden auf diese Weise in axialer Richtung etwas durchfedern können. 'wodurch eine wirksame Dämpfung der Seiteiikraft Q erreicht ist.If the wheel 2 swings through, the spring bars 41, 42 exert essentially the same moments on the links 16, 17 . The pivoting of the wheel 2 takes place around the connecting line of the Kuge1zaapfen 8, 9 as a steering axis. If a transverse force Q acts on wheel 2, as shown in FIG. This tilting moment acts on the links 1 6, 1 7 in the form of a pair of forces S # h, if! A means the vertical distance between the pivot pins 23, 24. A tensile force S thus acts on the upper pivot pin 24 and a compressive force S acts on the lower support pin 23. Since the pivot pins 23, 24 are only held axially by the spring bars 44 42, the forces S are absorbed directly by them; the upper spring bar 42 is here under tension and the lower spring bar 4 1 under pressure. Since the elasticity of the spring bars 44 42 under axial forces is naturally too low to ensure the desired resilience, the spring bars 4r, 42 are slightly pre-curved so that bending and buckling loads take the place of the tensile and compressive loads. The _Trehzapfen 23, 24 will be able to deflect somewhat in this way in the axial direction. 'whereby an effective damping of the side force Q is achieved.

Wem ein Federstab bricht, dann geht die Führung der -Drehzapfen 23, 24 nicht verloren, weil die Schraubenbolzen 39, 40 als. Anschläge wirken und die axiale Bewegung der Tragzapfen 23, 24 begrenzen. Die Körnerschrauben 53, 54 brauchen praktisch nicht die volle Kraft S zu übertragen, weil die Vierkante 43, 44 durch die Auflagerdrücke beider Wagenseiten unter Reibungsschluß stehen. Nach Entfernung der Schrauben 39, 4o und 53, 54 oder auch der Stifte 39, 39a sind die Federstäbe 4 i , 42 in sehr einfacher Weise auszubauen.If a spring bar breaks, then the guide of the pivot pin 23, 24 not lost because the screw bolts 39, 40 as. Attacks work and the limit the axial movement of the support pins 23, 24. The center screws 53, 54 need practically not to transmit the full force S, because the square 43, 44 through the bearing pressures on both sides of the car are frictionally engaged. After removal the screws 39, 40 and 53, 54 or the pins 39, 39a are the spring bars 4 i, 42 to expand in a very simple manner.

Die Erfindung* ist nicht auf dieses Ausführungsbeispiel beschränkt. Es kann jede Art von Drehfedern verwendet werden, z. B. auch zylindrische Schraubenfedern, deren Hubfederung -unabhängig von der Drehfederung einstellbar ist. Wie die Tragzapfen der Lenker und die mit ihnen verbundenen Drehfedern an sich im Rahmen gelagert sind, ist für die Erfindung ohne Belang.The invention * is not restricted to this exemplary embodiment. Any type of torsion spring can be used, e.g. B. also cylindrical coil springs, whose lifting suspension can be adjusted independently of the torsion suspension. Like the trunnions the handlebars and the torsion springs connected to them are mounted in the frame, is irrelevant to the invention.
